You've only compensated for the loss of income for a total of 480 days, though. That'll let one parent work 75% for about five years, while earning about 95% of their full time salary.
First of all only you're only fully compensated 360 of those 480 days, for the other 120 days you only get the minimum level of compensation. Secondly it depends on what their full time salary is. There is a hard upper limit on how much you can get compensated, and most people with good jobs are quite a bit over that limit. So someone with a higher paying job might only get 40-50% of his salary.
